We extend the generalized method of moments to a setting where a subset of the parameters may vary over time with unknown dynamics. We approximate the true unknown dynamics by an updating scheme that is driven by the influence function of the conditional criterion function at time t. The updates...

integrated series may induce spurious causality, even if, they are used in differenced form. It is observed that in general the …

In this paper we consider different periodic extensions of regression models with autoregressive fractionally integrated moving average disturbances for the analysis of daily spot prices of electricity. We show that day-of-the-week periodicity and long memory are important determinants for the...

The output gap plays a crucial role in thinking of many inflation targeting central banks yet, the real time estimates of the output gap undergo substantial revisions as more data become available. In this paper, we use the state space framework to augment the simple Hodrick-Prescott filter with...
